DGS-3024 Gigabit Ethernet Switch Manual

 

Spanning Tree 

This Switch supports three versions of the Spanning Tree Protocol; 802.1d STP, 802.1w Rapid STP and 802.1s MSTP.  802.1d 
STP will be familiar to most networking professionals. However, since 802.1w RSTP and 802.1s MSTP has been recently 
introduced to D-Link managed Ethernet Switches, a brief introduction to the technology is provided below followed by a 
description of how to set up 802.1d STP, 802.1w RSTP and 802.1s MSTP. 

802.1s MSTP 

Multiple Spanning Tree Protocol, or MSTP, is a standard defined by the IEEE community that allows multiple VLANs to be 
mapped to a single spanning tree instance, which will provide multiple pathways across the network. Therefore, these MSTP 
configurations will balance the traffic load, preventing wide scale disruptions when a single spanning tree instance fails. This will 
allow for faster convergences of new topologies for the failed instance. Frames designated for these VLANs will be processed 
quickly and completely throughout interconnected bridges utilizing either of the three spanning tree protocols (STP, RSTP or 
MSTP).  

This protocol will also tag BPDU packets so receiving devices can distinguish spanning tree instances, spanning tree regions and 
the VLANs associated with them. These instances will be classified by an MSTI ID. MSTP will connect multiple spanning trees 
with a Common and Internal Spanning Tree (CIST). The CIST will automatically determine each MSTP region, its maximum 
possible extent and will appear as one virtual bridge that runs a single spanning tree. Consequentially, frames assigned to different 
VLANs will follow different data routes within administratively established regions on the network, continuing to allow simple 
and full processing of frames, regardless of administrative errors in defining VLANs and their respective spanning trees. 

Each Switch utilizing the MSTP on a network will have a single MSTP configuration that will have the following three attributes: 

1.  A configuration name defined by an alphanumeric string of up to 32 characters (defined in the 

Current MST 

Configuration Identification 

window in the Configuration Name

 

field). 

2.  A configuration revision number (named here as a Revision Level (0-65535) and found in the 

Current MST 

Configuration Identification 

window) and; 

3.  A 4096-element table (defined here as a VID List in the 

Current MST Configuration Identification

 window) that will 

associate each of the possible 4096 VLANs supported by the Switch for a given instance. 

 To utilize the MSTP function on the Switch, three steps need to be taken: 

1.  The Switch must be set to 

MSTP

 (found in the

 STP Bridge Global Settings

 window in the STP Version field) 

2.  The correct spanning tree priority for the MSTP instance must be entered (defined here as a Priority in the 

STP Instance 

Table

 window when configuring the settings for an MSTI ID). 

3.  VLANs that will be shared must be added to the MSTP Instance ID (defined here as a

 

VID List

 

in the

 Current MST 

Configuration

 

Identification

 window when configuring the settings for an MSTI ID). 

802.1w Rapid Spanning Tree 

The Switch implements three versions of the Spanning Tree Protocol, the Multiple Spanning Tree Protocol (MSTP) as defined by 
the IEEE 802.1s, the Rapid Spanning Tree Protocol (RSTP) as defined by the IEEE 802.1w specification and a version 
compatible with the IEEE 802.1d STP. RSTP can operate with legacy equipment implementing IEEE 802.1d, however the 
advantages of using RSTP will be lost.   

The IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) evolved from the 802.1d STP standard. RSTP was developed in order to 
overcome some limitations of STP that impede the function of some recent Switching innovations, in particular, certain Layer 3 
functions that are increasingly handled by Ethernet Switches. The basic function and much of the terminology is the same as STP. 
Most of the settings configured for STP are also used for RSTP. This section introduces some new Spanning Tree concepts and 
illustrates the main differences between the two protocols.
